Honest comparison · no hype
Specialist Partner or Generic Dev Shop:
what's the difference?
CAD automation isn't standard software. Without domain knowledge of parametric modeling and BOM generation, teams pay for a learning curve and own fragile systems.
At a glance
Where the Two Routes Differ
The core difference
What "Engineering-First" Actually Means
A generic developer builds what you describe. If you describe it well, you get what you asked for. If you miss something like a special case in how SolidWorks handles multi-body parts, or how Inventor assembly constraints propagate, you find out during testing, not during specification. FDES engineers have built these systems before. They know where the gaps show up before you do.
The second difference is maintenance. Generic outsourced code often works at handover but becomes fragile over time, especially when the original developer is no longer available. Engineering automation systems need to survive CAD version updates, new product variants, and team changes. Production-grade code, proper documentation, and structured handover are not optional extras.
That said, generic outsourcing is the right call for genuinely standard software work. If you need a data migration script, a reporting dashboard, or a basic web form, there is no reason to pay specialist rates.
Side by side
Feature Comparison
| Feature | Generic Dev Outsourcing | FDES Technologies |
|---|---|---|
| CAD Platform Knowledge | Project-by-project, learned at client expense | 19+ years across Inventor, AutoCAD, Revit, SolidWorks |
| Understanding Engineering Logic | Codes what the client specifies | Engineers who know IS codes, tolerances, design rules |
| Code Documentation | Varies by vendor and contract | Full documentation + handover training included |
| CAD Version Update Support | Depends on vendor availability | Experienced with Autodesk upgrade cycles |
| Production-Grade Quality | Quality depends on vendor tier | Engineering-grade systems built for long-term use |
| Project Pricing | Quote-based, often opaque | Transparent ($5K–$150K+ published) |
| Engineering Calculations | Codes what you specify (may miss edge cases) | Can build and validate calculation engines |
| Source Code Ownership | Depends on contract. Verify the terms carefully. | Always yours, clearly contracted |
| Post-Delivery Support | Varies widely | Structured warranty and support options |
| Risk of Key-Person Dependency | High. Often a single developer. | Low. Team-built and documented. |
Being fair
Where Generic Outsourcing Still Makes Sense
A specialist is not always the right answer. If your project falls into any of the categories below, a good generic developer or dev shop will serve you well and you will not need to pay engineering-specialist rates.
Standard Web Applications
Web applications with no CAD dependency, customer portals, internal tools, marketing sites. These don't require CAD domain knowledge. A competent web developer is the right hire.
Database Integrations
If you're connecting an ERP to a CRM, or migrating data between platforms, and neither system touches CAD workflows, a generic integration developer handles that well.
Mobile Apps for Field Teams
Inspection apps, punch-list tools, and field reporting apps are standard mobile development work. No specialist CAD knowledge required.
Reporting and Dashboards
Business intelligence dashboards, KPI reports, and data visualisation tools are well within the scope of a general-purpose development team.
Fully Specifiable Requirements
Any project where the requirements can be fully described upfront, with no domain knowledge needed to spot gaps, is a good fit for generic outsourcing. The risk appears when specification requires engineering judgment.
The gap, visualised
Where Engineering Automation Sits
CAD automation lives at the intersection. A developer without engineering knowledge builds to the spec you write. FDES engineers bring the domain knowledge that keeps you from writing an incomplete spec in the first place.
Questions to Ask Any Automation Vendor
Before committing to an outsourcing partner for CAD automation work, run through these questions. The answers tell you quickly whether the firm has done this before or will be learning on your time.
- Which CAD versions have you built production automation for?
- Can you show code from a previous Inventor or AutoCAD automation project?
- How do you handle CAD API deprecations across version upgrades?
- Who maintains the system if your lead developer leaves?
- Is full source code and documentation included at handover?
- What happens if a parametric relationship breaks after a SolidWorks update?
At project completion
What FDES's Handover Includes
The system you receive works. So does everything around it.
Source Code
Full, commented codebase with no black boxes. Every function is documented. You own it outright from day one.
Documentation
Technical specification, user guide, and maintenance notes. Written so your own team can pick it up, not just the person who built it.
Training
Live walkthrough session with your engineering team covering day-to-day use, configuration changes, and what to do when something unexpected happens.
Warranty Period
30-day bug-fix warranty post go-live. If something breaks in production that we missed in testing, we fix it. No additional charge.
